You are, in fact, wrong.
What a vasectomy basically entails is that they sever the tubes that carry sperm from your balls up to your prostate (where it then comes out your penis) and seal them. Basically, when a guy orgasms, the sperm is sealed inside his balls. There is no effect on sensory input, and therefore, feels just as great as normal.

So the sperm gets blocked? Wouldn't that "register" to the body that sperm was ejaculated, then the body would make more sperm? And then eventually the sperm that was blocked, would die/rot and new sperm would continue to fill the vas deferns until it pops open inside the scrotum sack? Maybe I over analyzed.

Nope. Sperm cells are just like any other cells, and thus, have a life-span of their own. Since new sperm is being continuously being produced, the old, dead cells are carried off to be disposed of through the digestive tract. So, every time you take a crap, there are hundreds of thousands of dead sperm cells in there.
Fun fact: The reason that crap is brown, is that a large portion of it is made up of dead blood cells being disposed of.

It has a minute chance of naturally reversal (0.1% to 1%, depending on sources).
It can also be reversed surgically by preforming a so called vasovasostomy which is effective in 55% of cases if preformed within 10 years of the vasectomy and 25% if preformed after 10 years.
